So far, Fisch hasn't had to worry about that. Fisch said Thursday prior to practice that Bortles has shown quality retention of the scheme in the five-week break between the offseason program and training camp.

"One of the things we asked of him was to come in here and not just start from Day One again," Fisch said. "We didn't want Groundhog Day. We didn't want a repeat performance. We didn't want it to be like nothing has changed from the day before. So, how much does he know and recall? What he showed me is he actually dug deeper into the plays."

Fisch said Bortles is playing faster, understanding the system and his reads.

"One of the things you worry about is how does a guy handle something he's never done before," Fisch said. "He's had OTAs and minicamp. Now, he's got four weeks to figure out what he's going to do. I thought he really prepared, so he came back ahead of where I thought he was going to be."

Bortles, the third-overall pick in May's draft, remains the backup quarterback behind veteran Chad Henne. The Jaguars have utilized the 6-foot-5, 230-pound Bortles on many rollouts in team drills, giving the offense an extra edge.

"I love the fact that when Blake moves, he's a strong, tough guy to bring down," Fisch said. "He also throws the ball nicely on the move. It's something clearly he's done throughout his career in college. That's part of our system, so they have to do that."
